HINGE.

' Specification of team rum.

Patented July 23, 1912.

Application filed October 28, 1911. Serial No. 856,132.

To all whom it may concern:

Be it known that I, Mmo HARRIS, a citizen of the United States, residing at J amestown, in the county of Chautauqua and State of New York, have invented new and of which the following, taken in connection with the accompanyin drawings, is a specification.

The invention relates to hinges for doors and windows; and the object of my improvement is to provide a strong and durable hinge which has great frictional holding power so as to hold a door or window at that point to which it is turned, rendering the hinge particularly adaptable to hinge doors and windows for ventilation purposes, for the door or window which is used as a ventilator may be turned to any desired degree of opening and the hinges will hold the ventilator at that point without other support; and the invention consists in the construction and arrangement of the parts as shown in this specification and the accompanying drawings and pointed out in the claims.

In the drawings, Figure 1 is an elevation of a window with each of the sash provided with a ventilator having my hinges for holdg the same. Fig. 2 is a sectional view at line X X in Fig. 1 of the upper sash ventilator and frame, showing the ventilator held in the open position by the frictional control of the hin es. Fig. 3 is a sectional view at line Y Y in Fig. 4 showing the manner of attachment preferred for obtaining the frictional holding of the hinge. F i 4 is an elevation of the hinge as attac ed to the window or door and the frame. Fig. 5 is a detail plan view of one plate of the hinge before it is bent up into form; and Fig. 6 is a similar view of the other plate. Fig. 7 is an endwise view of the assembled hinge. Fig. 8 shows detail edgewise and of'the pin for holding the parts together and showing the flattened central portion.

Like numerals of reference refer to corresponding parts in the several views.

The hinge is composed of two plates 10 and 11, w ich are preferably struck from sheet steel by means of suitable dies; and a 'n 12. The pin 12 is made round with a flattened central portion 13 and round end portions 14. The end portions 14 may be serrated or otherwise roughened in order to obtain alarger gripping hold upon the same,

but such methods of toughening to obtain frictional hold are not usuallyv found necessary, since the smooth round end portions 14 give suflicient frictional contact and are more durable and convenient in use. The plate 10 is made in the U-sha ed form with the two end tongues 15 which are bent around the end portions 14 of the pins 12. The ends of the tongues 15.are bent at an angle away from the main portion of the plate 10,as shown in Figs. 3 and 7, so that said tongues obtain a strong frictional grip upon the'entire surface of the frictionalends 14. The plate 10 is provided with screw holes 16 along the main portion of the plate, and screw holes 17 in the ends of the tongues 15, and the length of the tongues 15 is so roportioned that when said tongues are ent around the end portions 14 of the pins 12 the holes 17 in the ends of the tongues will coincide with the holes 16 to receive therethrough the attaching screw bolt 18.

The screw bolt 18 preferably" has its nut inset in a hole 19, as shown in Fig. 3, so that it holds firmly upon the window or door and provides a rigid holding means for the spring tongues 15. It is apparent that with this arrangement sprin tongues 15 can be drawn up to any desire degree of frictional .grip upon the ends 14 and the use of the screw bolts greatly strengthens the entire construction, for it is apparent that in soft woods a common screw might be withdrawn from the wood by the gripping strain. In those materials, however, in which a common screw would hold firmly the screw bolts are unnecessary. The plate 11 is formed with the central tongue 20 which fits between tongues 15 and is so proportioned as to bend around the flattened portion 13 of the pin 12 so that the screw hole 17 in the end of the tongue will coincide with the central screw hole 16 in the main portion of the plate. The tongue 20 is pressed onto said flattened portion by means of a suitable die so that the pin is firmly held by the plate 11 and cannot turn therein when the attaching screw is inserted. By flattening the center of the pin and permanently .screwing the center leaf thereto by means of the atmits of the entire hinge being made by means of suitable dies and presses.

The hinge is assembled in the following manner: The plate 11 is bent around the flat portion 13 of the pin 12, thereby rigidly attaching plate 11 to the pin 12 and forming the fixed member of the hinge. The tongues 15 on the plate are bent around the round ends 14 of the pin 12 and bent at an angle from said plate 10 to give the desired frictional tension in the grip of the tongues 15 upon the parts 14, thereby forming the movable member of the hinge. It is apparent that the fixed member of the hinge may be attached to the frame and the movable member to the window, door or ventilater and that any desired frictional tension may be given to the spring tongues 15 upon the parts 14 of the pin 12, so that when two hinges are placed upon a ventilator, as shown in Fig. 1, the ventilator may be open,

as shown in Fig. and will be firmly held at the desired angle or degree of opening therefor. For convenience in opening an upper ventilator or one that is out of reach, a cord 21 and pulley 22 may be attached to the ventilator and frame so that the ventilator may be opened and closed by pulling upon one or the other ends of the cord, but the cord 21 is unnecessary for holding the \entilator in the withdrawn position, the hinges by their 'rictional control hold the ventilator as hercinbefore described.

it is obvitus that any desired number of tongues 15 or may be made upon the 2 plates 10 and 11, and that the pin 12 may be made with a plurality of flattened portions similar to that shown at 13 but corresponding to the number of tongues 20 upon the plate 11 and the number of tongues 15 on the plate 10 must correspond to the number of round portions 14 on the pin. In this manner a strong frictional holding hinge may be easily provided.

The flattening of the part 13 of the pin 12 is the simplest and surest method of fixedly attaching the plate 11 to said pin to form the fixed member of the hinge, but any other mannerof construction whereby the tongue 20 was iven a fixed hold upon the pin 12 would a tain my purpose.

I claim as new:

1. A friction hinge comprising two sheet.

metal members, a connecting pin, one of said sheet metal members fixedly aftaehed by a central tongue to said pin, tongues on the other sheet metal member encircling said pin one each side of said central tongue and extending out at a spaced distance from said member, and attaching screws through said tongues and member to obtain a frictional grip on each end of said pin, substantially as shown and described.

2. A friction hinge comprising two sheet metal members, tongues on said sheet metal members, a connecting pin, a flattened central portion of said pin to receive the tongue of one of said sheet metal members in fixed attachment thereabout, round end portions on said pin each side of said flattened portion and tongues on the other sheet metal mem ber encircling the round end portions of said pin and extending at a spaced angle from the other portion of said member to obtain a frictional holding on said round end portions by means of suitable attaching screws.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
